Abstract

The invention discloses an aquifer drainage feasibility analysis method based onhydrological exploration and a dewatering test, which comprises the steps that A, a water-rich anomaly area is exploredby geophysical prospecting; B, the water-rich anomaly area is verified by drilling; C, a drainage feasibility dewatering test is designed; D, a dewatering test is carried out, and data collection is completed; E, the result of the dewatering test is analyzed; and F, aquifer drainage feasibility is synthetically analyzed. According to the aquifer drainage feasibility analysis method based on the hydrological exploration and dewatering test, the range of a main water-filled aquifer water-rich anomaly area is determined, and a reference for the drilling engineering arrangement is provided, and accuracy and the efficiency of the drilling water exploration are improved; more direct data can be obtained to accurately evaluate the aquifer drainage feasibility, and at the same time aquifer drainage amount and drainage time can be effectively predicted; an observation hole water bursting coefficient in each time period of the drainage process can be calculated, a contour map of the water bursting coefficient can be drawn, the safety range change after drainage in each time period can be analyzed, and the aquifer drainage feasibility is synthetically analyzed in combination with hydrogeological parameters, mine drainage capacity, drainage time, drainage amount and the like.

Description

technical field [0001] The invention relates to a technology for preventing and controlling coal mine water disasters, in particular to a method for analyzing the feasibility of dredging aquifers based on hydrological exploration and water discharge tests. Background technique [0002] Coal mine water disaster prevention and control is the top priority of coal mine safety production work. For the prevention and control of coal seam floor water hazards, the coal seam floor aquifer grouting reconstruction technology is mainly used to carry out grouting reconstruction in areas with a high possibility of water inrush on the coal seam floor, or the coal seam floor aquifer drainage and pressure reduction technology is used to drain and reduce pressure in dangerous areas. The use of the above-mentioned measures has avoided the occurrence of water damage accidents to the greatest extent and realized safe mining. [0003] Among them, the drainage and depressurization technology is t...
